Problems solved by technology

However, when the cooling water inlet temperature drops below an arbitrary temperature, since the pressure difference between the high-temperature regenerator and the condenser decreases as the pressure of the high-temperature regenerator decreases, if the flow path is installed as in the above-mentioned conventional absorption refrigerator resistance mechanism, the fluidity of the refrigerant decreases
If the fluidity of the refrigerant liquid decreases, the refrigerant liquid accumulates near the low-temperature regenerator in the refrigerant pipe, or the refrigerant liquid travels to and from the low-temperature regenerator in the refrigerant pipe. The heat regeneration of the absorption liquid becomes unstable, and even fluctuations in the temperature at the outlet side of the brine supplied to the heat load may occur repeatedly up and down

[0037] figure 1 It is a schematic configuration diagram of the absorption refrigerator of the first embodiment.

[0038] The absorption refrigerating machine 100 is a dual effect type absorption refrigerating machine using water as a refrigerant and a lithium bromide (LiBr) aqueous solution as an absorbing liquid. Such as figure 1 As shown, the absorption refrigerator 100 includes: an evaporator 1; an absorber 2 arranged in parallel with the evaporator 1; an evaporator-absorber casing 3 for accommodating the above-mentioned evaporator 1 and absorber 2; High-temperature regenerator 5; low-temperature regenerator 6; condenser 7 arranged in parallel with the low-temperature regenerator 6; low-temperature regenerator condenser housing 8 for accommodating the above-mentioned low-temperature regenerator 6 and condenser 7; low-temperature heat exchanger 12; Heat exchanger 13; refrigerant discharge heat recovery device 16; thin absorption liquid pump P1; thick absorption liquid pump...

no. 2 approach

[0063] In the first embodiment, the control device 50 controls the on-off valve 43 based on the measurement result of the cooling water temperature sensor 62 , but in the second embodiment, the control device 50 controls the on-off valve 43 based on the measurement result of the cooling water temperature sensor 62 and the fuel The on-off valve 43 is controlled by controlling the opening degree of the valve 4B.

[0064] The cause of refrigerant stagnation is not only the pressure difference between the high temperature regenerator 5 and the condenser 7, but also the amount of refrigerant vapor generated in the high temperature regenerator 5, the opening degree of the fuel on-off valve 4B and the The ratio of the amount of refrigerant vapor generated to the maximum amount of refrigerant vapor generated in the high-temperature regenerator 5 has a substantially proportional relationship. Therefore, in this embodiment, the pressure difference between the high-temperature regenerato...

Abstract

The invention provides an absorption refrigerator which can be stably operated even if the cooling water is low in temperature, and comprises a high temperature regenerator (5), a low temperature regenerator (6), an evaporator (1), a condenser (7) and an absorber (2). The high temperature regenerator (5) is connected to the condenser (7) through a refrigerant pipe (31) of the low temperature regenerator (6). The refrigerant pipe (31) is provided with a flow path resistance mechanism (41) applying a flow path resistance and a bypass pipe (42) bypassing the flow path resistance mechanism (41). The bypass pipe (42) is provided with an open and close valve (43) where cooling water circulates in the cooling water pipes (15) of the absorber (2) and the condenser (7). A cooling water temperaturesensor (62) for measuring the temperature of cooling water and a valve control mechanism (50) which controls the valve based on the measuring result of the cooling water temperature sensor are disposed at the absorber inlet side of the cooling water pipe.

Description

technical field [0001] The present invention relates to an absorption refrigerating machine including a damper in a refrigerant pipe that sends refrigerant from a high-temperature regenerator to a condenser. Background technique [0002] At present, there is known an absorption refrigerating machine that is equipped with a high-temperature regenerator, a low-temperature regenerator, a condenser, an evaporator, and an absorber and connects them with pipes to respectively form circulation paths of an absorption liquid and a refrigerant (for example, refer to Patent Document 1). In this absorption refrigerating machine, the high-temperature regenerator and the condenser are connected through a heat transfer pipe arranged in an absorption liquid storage part of the low-temperature regenerator and a refrigerant pipe of a refrigerant discharge heat recovery device. The refrigerant vapor heated by the high-temperature regenerator and separated from the absorption liquid is condens...
